Abstract

Solid state electronic cameras are made modular so that replacement of inoperative CCD imagers can be done quickly and inexpensively by storing in the camera heads the operating parameters of each of a variety of imagers such as charge coupled device imagers. A camera head with a replacement imager communicates to a resident controller the parameters of the replacement imager selected. Operating parameters such as clock pulse signals may, in addition, be varied as to pulse width and frequency. The parameters are stored in an address set in a look up table in association with imager identifications.

Claims

1. A solid state imaging camera system including a camera head, said head being configured to accept any one of electronically a variety of different solid state imagers, said head including a plurality of look up tables, one for each one of said variety of imagers, means for storing in associated ones of said look up tables codes representing the operating parameters of different ones of said variety of different imagers, and means for communicating to an electronically coupled controller the codes stored in the associated look up table for the selected one of said variety of imagers.

2. A solid state imaging camera system as set forth in claim 1 including a camera body wherein said camera body includes said controller, said controller including storage means and means for interrogating said camera head for transferring to said storage means in said controller from said associated look up table the codes representing the operating parameters of said selected imager.

3. A solid state imaging camera system as set forth in claim 2 wherein said associated look up table in said camera head includes a static random access memory, said controller including means for transferring from said random access memory from the associated look up table therein the codes representing the operating parameters of said selected imager.

4. A solid state imaging camera system as set forth in claim 1 wherein said solid state imagers comprise charge coupled devices.
